Key Takeaways
- A REG-03 is a notice seeking clarification on your GST registration application. It is not a rejection. It means the officer wants more information before approving.
- You must reply in FORM GST REG-04 within 7 working days of receiving the REG-03. Miss the deadline and the officer can reject the application in FORM GST REG-05.
- Most REG-03 notices are triggered by the same handful of issues: unclear address proof, a name mismatch on the electricity bill, a missing consent letter or NOC, or a vaguely described business activity.
- Reply with documents that directly answer the query. Do not upload a generic bundle. A targeted, correct REG-04 usually gets approved in one go.
- After a satisfactory REG-04, the officer has 7 working days to approve and issue your GST certificate in REG-06.
You applied for GST registration, and instead of an approval you got a REG-03. It is easy to read this as a rejection and panic. It is not. A REG-03 is the GST officer saying "I need one or two things cleared up before I approve you." Handle it correctly and your registration goes through in days. Handle it poorly, or ignore the clock, and the application is rejected and you start over.
This guide tells you exactly why REG-03 notices are issued, how to file the REG-04 reply, what to attach, and how to word it.

What REG-03 and REG-04 Actually Are
The registration flow has a simple logic. You apply, the officer reviews, and if anything is unclear the officer asks before deciding.
Step-by-Step Guide
How the REG-03 Stage Fits the Registration Flow
The clarification loop, end to end
You apply (REG-01)
You submit your GST registration application with PAN, Aadhaar, business and address proof.
ApplicationOfficer raises a query (REG-03)
If the officer is not satisfied, a REG-03 notice is issued, usually within 7 working days of the application, listing exactly what needs clarification.
NoticeYou reply (REG-04)
You file FORM GST REG-04 within 7 working days of receiving the REG-03, answering each query and attaching the supporting documents.
Your replyOfficer decides
If satisfied, the officer approves and issues the GST certificate in REG-06. If not satisfied, or you do not reply in time, the application is rejected in REG-05.
DecisionSource: CGST Rules 2017, Rule 9; FORM GST REG-03, REG-04, REG-05, REG-06
The single most important number here is 7 working days. That is your window to file REG-04 from the date the REG-03 lands. Working days, not calendar days, but do not gamble on the difference. Reply early.
The Common Reasons a REG-03 Is Issued
Almost every REG-03 traces back to a short list of fixable problems. Knowing them lets you pre-empt the query, or answer it cleanly.
| Trigger | What the officer is questioning | What fixes it |
|---|---|---|
| Unclear or blurry document | Upload is illegible or cropped | Re-upload a clear, full-page colour scan |
| Address proof mismatch | Principal place of business proof does not match the address entered | Consistent address across the bill, agreement, and application |
| Electricity bill not in your name | Premises proof is in the owner's or a third party's name | Add a rent agreement plus a consent letter or NOC from the owner |
| Missing consent letter or NOC | Premises are shared, rented, or owned by family | Upload a signed consent letter or no-objection certificate |
| Nature of possession unclear | Officer cannot tell if the place is owned, rented, or consented | State possession clearly and back it with the matching document |
| Vague business activity | HSN or SAC and business description do not align | Describe the actual goods or services with correct HSN or SAC codes |
| Photo or signature mismatch | Promoter photo or details do not match PAN or Aadhaar | Upload a recent photo and verify Aadhaar authentication |
In April 2025 the CBIC issued Instruction No. 03/2025-GST standardising the documents officers may demand and directing them not to raise presumptive or irrelevant queries during registration. If your REG-03 asks for something outside the prescribed list, you are within your rights to politely point this out in your REG-04 while still providing what is genuinely required.
How to File Your REG-04 Reply, Step by Step
You file REG-04 directly on the GST portal against the ARN of your application. You do not need a fresh login if you use the application-tracking route.
Step-by-Step Guide
Filing FORM GST REG-04 on the Portal
From notice to submission
Open the clarification form
On gst.gov.in, go to Services, then Registration, then Application for Filing Clarifications. Enter the ARN or the reference number of the REG-03 notice.
Step 1Read each query carefully
The portal shows every point the officer raised. Address each one specifically. A blanket reply is the most common reason a second query is issued.
Step 2Enter clarification and upload documents
Type a clear response to each query and attach the exact supporting document that answers it. Keep files clear, in colour, and within the size limit.
Step 3Submit with DSC or EVC
Verify and submit using a Digital Signature Certificate (mandatory for companies and LLPs) or EVC via OTP. Save the acknowledgement.
Step 4Source: GST portal (gst.gov.in), Application for Filing Clarifications
Supporting Documents to Keep Ready
Match the document to the query. Attaching the right proof is what gets a one-shot approval.
- Address and premises proof: latest electricity bill, property tax receipt, or municipal khata; rent or lease agreement if rented.
- Ownership or consent: a consent letter or NOC from the premises owner where the property is not in the applicant's name, on plain paper, signed.
- Identity: PAN and Aadhaar of the promoters, a recent passport-size photo, and proof of Aadhaar authentication.
- Constitution: partnership deed, certificate of incorporation, or registration certificate, as applicable to your entity.
- Bank proof: a cancelled cheque or the first page of the passbook, if asked.
Sample REG-04 Reply Formats
Keep replies short, factual, and tied to the attachment. Two examples.
Query: Principal place of business proof not satisfactory. Reply: "The registered premises are taken on rent. We attach the registered rent agreement dated [date] and the latest electricity bill in the owner's name, along with a signed consent letter from the owner permitting use of the premises for business. The address in all documents matches the address in the application."
Query: Nature of business activity unclear. Reply: "The business supplies [describe goods or services] under HSN/SAC code [code]. We attach a sample purchase invoice and our business description for reference. The activity is correctly reflected in the application."
Notice the pattern: state the fact, name the attached document, confirm consistency. No arguing, no padding.
What Happens After You File REG-04
Once you submit, the officer reviews again and has 7 working days to act. Three outcomes are possible:
- Approved: the officer is satisfied and issues your GST registration certificate in FORM GST REG-06, with your GSTIN.
- Rejected: if the clarification is still inadequate, the application is rejected in FORM GST REG-05 with reasons. You can apply afresh, addressing the stated gaps.
- No reply filed: if you let the 7-day window lapse without filing REG-04, the officer can reject the application outright. This is the avoidable failure.
The lesson is simple. A REG-03 is an opportunity to fix one or two things, not a verdict. Reply fast, reply specifically, and attach the exact proof for each query.
